tty: serial: 8250: Merge duplicate conditions

Browse Source 
This patch refactors a switch case statement by merging an if condition
in the default case into an identical condition right after the switch
statement.
This comes with a slight change in behaviour: If pci_netmos_9900_numports
returns 0, an additional warning is printed.
